IMPROVED WASHING-MACHINE.

Specification forming part of Letters'nPatent No. 53,793, dated April10, 1866.

To all whom it may concern:

Be it known that I, DAVID DENNIsoN, of Annisquam, in the county of Essexand State of Massachusetts, have invented a new and ImprovedClothes-Washing Machine; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable thoseskilled -in the art to make and use the same, reference beillg had tothe accompanying drawings, forlning part of this specification, inwhich- Figure l is a side sectional view of nly invention, taken in theline a: x, Fig. 2; Fig. 2, a transverse vertical section of the salne,taken in the lille y y, Fig. l.

Similar letters of reference indicate correspollding parts.

This invention relates to a new alld iln` proved clotlleswashing machineof that class in which a liuted pressure-roller is employed inconnection with a slatted bed.

The object of the invention is to obtain a machine of the classspecified which will act uniformly upon the clothes, subject all partsof them to an equal pressure and frictioll, and cleanse them withoutinjury.

A represents a suds-box supported at a suitable lleigllt by legs a, alldhaving all upright, B, secured to each side of it, the upper ends ofsaid uprights beillg collnected by a crosspiece, b. In the bottom ofthis suds-box there is placed a slatted frame, (l, the slats having atransverse position and placed at equal distances apart, spaces beingallowed between them for the water or snds to pass through. Tllisslatted frame C has a central longitudinal strip, D, which rests on thebottom of the snds-box and allows it to tilt ol'incline laterally, so asto conform to all unequal thickness of a layer of clothes.

Dl D represent two swinging arms, the upper ends of which are suspendedon pills c c in the uprights B B, said pins passing through oblong slotsd d in the swinging arms. (See Fig. l.) These arms D D are connected bya cross-bar, c, and also by a box, f, and between the lower ends ofthese arms a fluted roller, E, is fitted on journals or a shaft.

The roller E is formed of slats g, secured to circular heads It, whichvform thev ends of the roller, spaces being allowed between the slats forthe water to pass through, as shown in Fig. l.

To the cross-bar c of thearms Dl D', and to the cross-piece b of theuprights B B, a spiral spring, F, is attached, which partially sustainsthe roller E, relieving the clothes on the slatted frame C of a portionof its weight.

To each of the swinging arms Dl a bar, G, is attached by a pivot, t'.These pivots z' pass through oblong slotsj in the upper parts ot' thearms D', alld the lower ends of the arms are connected by pivots 7c tothe uprights B B alld to bars H, and these are connected by crosspiecesZ l.

From this description it will be seen that by workin g the bars H up anddown the roller E will be lnade to travel forward and backward over thewhole length ofthe slatted frame C. The clothes are placed on thisfralne and are subjected to the requisite degree of press ure andfriction by the roller E. In case a greater pressure is required the boxf lnay be loaded with any material. This may be necessary in washingheavy clothes.

The slatted frame C and roller E allow the water to pass through them,alld the snds will be forced through the texture of the clothes and thedirt eftectually cleansed therefrom, while the tilting of the frame Claterally causes it to coliform to any equality ofthe layer of clotheson the frame.

This machine, it is believed, conforms to or approaches in its operationnearer to the handrubbing process tllall any now ill use. The clothesare not liable to be injured by excessive friction and rubbing, and itmay be adapted, by graduating the pressure of the rollerE, towashingeither coarse or fine clothes.

Having tllus described my invention, I claim as new and desire to secureby Letters Patentl. The combination ofthe slatted frame O,pressure-roller E, bar D, swinging arms D D', bars G H, spring F, alldbox j', collstructed and arranged relatively to each other, andoperating ill the nlanner and for the purpose herein specified.

2. The arrangement of the swinging arms D D, bars Gr H, spring F, box f,and roller E, in the manner and for the purpose herein specified.
